The 14-day Bioconcentration test in rainbow trout was performed with radiolabelled Ethylhexyl Methoxycinnamate. During the first day, the concentration in the fish exposed to the lowest level (70 µg/l) increased to 32 µg/g fish, while the concentration in the fish exposed to the higher level (700 µg/l) increased to 49 µg/g. At the lower level the BCF remained rather constant between 279 and 433 with an average of 373. At the higher level, the concentration in the fish only slowly increased until day 2 and the BCF remained below 100 (64-76). However, on the last day the concentration in the fish had increased by more than a factor of two resulting in a final BCF of 175. Depuration of Ethylhexyl Methoxycinnamate out of the fish was exponential with a DT50 of 1.5 to 1.7 days and a DT90 of 5.0 to 5.5 days.
